摘　　要：随着电力市场方式多变,新能源占比逐步提高,原有离线策略能否满足电网实时运行需要进一步验证。首先研究稳控策略在线校核系统软硬件架构,采用可伸缩灵活分布式架构,方便模型和计算数据共享同步;研究稳控策略在线校核系统对外接口,从安稳主站获取安控站当值策略信息,从调度主站获取电网实时运行方式信息,从离线分析系统获取电网元件参数信息;研究策略在线校核总体计算流程,系统解析当值策略文件后,调用电气拓扑服务程序和名称匹配程序完成电网参数提取和实时计算拓扑生成,计算服务程序再根据当值策略中预想故障分析在实时方式中策略动作后的电网稳定性,将不稳定结果通过智能告警接口推送至调度主站,为调度人员提供辅助决策。With the electricity market changing in modes and the proportion of new energy gradually increased,it is necessary to further verify whether the original offline strategy can meet the real-time operation of the power grid.Firstly,the software and hardware architecture of the online checking system for stability control strategy is studied,and a scalable and flexible distributed architecture is adopted to facilitate the sharing and synchronization of model and computational data.The external interface of the online checking system for stability control strategy is studied to obtain the duty strategy information from the security master station,to get the real-time operation mode information of the power grid from the dispatching master station,and to acquire the parameter information of power grid components from the offline analysis system.The overall calculation flow of the online checking of the strategy is studied;the system parses the duty strategy file,and then calls the electrical topology service program and the name matching program to complete the grid parameter extraction and real-time calculation topology generation;service program is computed and subsequently,the stability of the power grid after the strategy action in real-time mode is analyzed according to the expected fault in the current duty strategy,with the unstable results sent to the dispatching master station through the intelligent alarm interface,so as to provide auxiliary decision-making for dispatchers.
